The BelAire QP318VLE is a 7.5 HP two-stage piston compressor designed for shops where noise matters as much as air supply. Its main differentiator is the high-strength ABS sound enclosure, which brings operating noise down to 69 dBA—less than half the noise level BelAire attributes to a standard piston compressor. Inside, a cast iron two-stage pump feeds an 80-gallon vertical ASME tank at up to 175 PSI, while the integrated high-flow fan manages airflow through the enclosure. The unit operates on 208-230V single-phase power and includes a magnetic starter.
The enclosure is more than a noise barrier: the forced-air cooling system is designed to move air through the cabinet while the panels reduce pump noise. That makes the compressor practical for locations where a conventional piston machine would be disruptive, provided the intake and exhaust areas remain unobstructed and the required ventilation clearances are maintained. The two-stage cast iron pump compresses air in two steps with cooling between stages, allowing the compressor to reach higher pressure while managing operating heat. An integrated aftercooler further lowers discharge temperature and helps remove moisture before compressed air moves downstream. Low-oil protection and high-temperature shutdown provide additional safeguards if lubrication or cooling becomes a problem.
This compressor is well suited to automotive service bays, small production areas, dealership workshops, and other commercial spaces where employees work near the compressor. It is particularly useful in shared or noise-sensitive buildings where isolating a conventional piston compressor is difficult. The vertical 80-gallon design keeps the floor footprint relatively compact, while the 69 dBA enclosure makes the machine a more practical option for spaces where conversations, customers, or neighboring businesses are nearby. Its 208-230V single-phase configuration also suits facilities without three-phase electrical service.

Confirm the air delivery figure before you order. A delivered-air rating is deliberately not printed on this page because the published figures are inconsistent. An air-delivery number is only useful if it is accurate. If air delivery is critical to your decision, ask us in writing and we will have BelAire confirm the figure before you order.
Certification, Stated Honestly
The product data states an ASME-certified tank and ASME safety valves. That certification applies to the pressure vessel and relief devices—the components responsible for containing and releasing 175 PSI.
The data does not state a nationally recognized testing-laboratory listing for the complete electrical assembly. That is a separate approval from an independent body and is not implied by the tank certification. If your insurer, workplace safety requirements or local electrical inspector requires one, confirm the requirement before ordering so we can verify the available documentation.
Shipping & Delivery
Ships by freight within the lower 48 states, with shipping priced live at checkout for your delivery address.
Plan unloading before delivery. You will need a forklift, loading dock or terminal pickup arranged with the carrier. Residential delivery carries an additional fee.
Inspect before signing. Check the crate and machine for visible damage, and record any issues on the bill of lading with the driver present. Photograph the shipment before it is moved or unpacked.
Warranty
A 2-Year consumer warranty is recorded for this compressor. The current warranty document is linked on this page and governs the coverage.
If the pump, motor or controls fail, photograph the problem, keep the assembly intact and contact us before disassembly. The manufacturer may need to inspect the failed component in its original condition. Follow the warranty instructions before removing or opening any components.
